You have a couple of switches with STP turned off -- someone plugs in some random cable, forming a bridge loop....... and everything continues running fine, until some time in the future when it all goes to hell in a hand-basket. Now, I could understand the system remaining stable until the first broadcast / unknown MAC caused flooding to happen, but I have seen this system remain stable for anywhere from a few days to in a few weeks before suddenly exploding.
If you want to hear about something whacked along those lines - imagine two access points which had spanning tree disabled, connected to a pair of switches on a vlan which wasn't running stp (thanks to platform stp limitations, the switches running pvstp and said campus having >800 vlans), and said ap's would occasionally associate in infrastructure mode - which would cause a broadcast storm on that vlan and fill trunk pipes with spaf. Debugging that one was hilarious. Hum. Adrian
